Thanks for looking and commenting everyone!
So excited about these finally blooming. Happy! Happy! Happy!
DeaC, if it's starting a new cane keep it in a bright spot and water regularly. In my experience, it doesn't need heavy watering, but does need an increase after winter. Also, unless the media looks like it's breaking down, I wouldn't bother moving it now. But if the media does look like it needs changing out, then now is probably the best time - the new growth will produce new roots and settle it into the new media. I have both potted and mounted, and they're doing equally well - I think it does prefer a more open mix though, but failing that, just let it dry out between waterings. I've found these plants to be pretty forgiving.
